<h2 class="title"><a name="DESCRIPTION">Description</a></h2>
<b>ippfind</b> finds services registered with a DNS server or available through local devices.
Its primary purpose is to find IPP printers and show their URIs, show their current status, or run commands.
<h3><a name="REGISTRATION_TYPES">Registration Types</a></h3>
<b>ippfind</b> supports the following registration types:
<dl class="man">
<dt>_http._tcp
<dd style="margin-left: 5.0em">HyperText Transport Protocol (HTTP, RFC 2616)
<dt>_https._tcp
<dd style="margin-left: 5.0em">Secure HyperText Transport Protocol (HTTPS, RFC 2818)
<dt>_ipp._tcp
<dd style="margin-left: 5.0em">Internet Printing Protocol (IPP, RFC 2911)
<dt>_ipps._tcp
<dd style="margin-left: 5.0em">Secure Internet Printing Protocol (IPPS, draft)
<dt>_printer._tcp
<dd style="margin-left: 5.0em">Line Printer Daemon (LPD, RFC 1179)
</dl>
<h3><a name="EXPRESSIONS">Expressions</a></h3>
<b>ippfind</b> supports expressions much like the
<b>find</b>(1)
utility.
However, unlike
<b>find</b>(1),
<b>ippfind</b> uses POSIX regular expressions instead of shell filename matching patterns.
If <i>--exec</i>, <i>-l</i>, <i>--ls</i>, <i>-p</i>, <i>--print</i>, <i>--print-name</i>, <i>-q</i>, <i>--quiet</i>, <i>-s</i>, or <i>-x</i> is not specified, <b>ippfind</b> adds <i>--print</i> to print the service URI of anything it finds.
The following expressions are supported:
<dl class="man">
<dt><b>-d </b><i>regex</i>
<dd style="margin-left: 5.0em"><dt><b>--domain </b><i>regex</i>
<dd style="margin-left: 5.0em">True if the domain matches the given regular expression.
<dt><b>--false</b>
<dd style="margin-left: 5.0em">Always false.
<dt><b>-h </b><i>regex</i>
<dd style="margin-left: 5.0em"><dt><b>--host </b><i>regex</i>
<dd style="margin-left: 5.0em">True is the hostname matches the given regular expression.
<dt><b>-l</b>
<dd style="margin-left: 5.0em"><dt><b>--ls</b>
<dd style="margin-left: 5.0em">Lists attributes returned by Get-Printer-Attributes for IPP printers and traditional <i>find</i> "-ls" output for HTTP URLs.
The result is true if the URI is accessible, false otherwise.
<dt><b>--local</b>
<dd style="margin-left: 5.0em">True if the service is local to this computer.
<dt><b>-N </b><i>name</i>
<dd style="margin-left: 5.0em"><dt><b>--literal-name </b><i>name</i>
<dd style="margin-left: 5.0em">True if the service instance name matches the given name.
<dt><b>-n </b><i>regex</i>
<dd style="margin-left: 5.0em"><dt><b>--name </b><i>regex</i>
<dd style="margin-left: 5.0em">True if the service instance name matches the given regular expression.
<dt><b>--path </b><i>regex</i>
<dd style="margin-left: 5.0em">True if the URI resource path matches the given regular expression.
<dt><b>-P </b><i>number</i>[<b>-</b><i>number</i>]
<dd style="margin-left: 5.0em"><dt><b>--port </b><i>number</i>[<b>-</b><i>number</i>]
<dd style="margin-left: 5.0em">True if the port matches the given number or range.
<dt><b>-p</b>
<dd style="margin-left: 5.0em"><dt><b>--print</b>
<dd style="margin-left: 5.0em">Prints the URI if the result of previous expressions is true.
The result is always true.
<dt><b>-q</b>
<dd style="margin-left: 5.0em"><dt><b>--quiet</b>
<dd style="margin-left: 5.0em">Quiet mode - just returns the exit codes below.
<dt><b>-r</b>
<dd style="margin-left: 5.0em"><dt><b>--remote</b>
<dd style="margin-left: 5.0em">True if the service is not local to this computer.
<dt><b>-s</b>
<dd style="margin-left: 5.0em"><dt><b>--print-name</b>
<dd style="margin-left: 5.0em">Prints the service instance name if the result of previous expressions is true.
The result is always true.
<dt><b>--true</b>
<dd style="margin-left: 5.0em">Always true.
<dt><b>-t </b><i>key</i>
<dd style="margin-left: 5.0em"><dt><b>--txt </b><i>key</i>
<dd style="margin-left: 5.0em">True if the TXT record contains the named key.
<dt><b>--txt-</b><i>key regex</i>
<dd style="margin-left: 5.0em">True if the TXT record contains the named key and matches the given regular expression.
<dt><b>-u </b><i>regex</i>
<dd style="margin-left: 5.0em"><dt><b>--uri </b><i>regex</i>
<dd style="margin-left: 5.0em">True if the URI matches the given regular expression.
<dt><b>-x </b><i>utility </i>[ <i>argument </i>... ] <b>;</b>
<dd style="margin-left: 5.0em"><dt><b>--exec </b><i>utility </i>[ <i>argument </i>... ] <b>;</b>
<dd style="margin-left: 5.0em">Executes the specified program if the current result is true.
"{foo}" arguments are replaced with the corresponding value - see SUBSTITUTIONS below.
</dl>
<p>Expressions may also contain modifiers:
<dl class="man">
<dt><b>( </b><i>expression </i><b>)</b>
<dd style="margin-left: 5.0em">Group the result of expressions.
<dt><b>! </b><i>expression</i>
<dd style="margin-left: 5.0em"><dt><b>--not </b><i>expression</i>

<h2 class="title"><a name="EXAMPLES">Examples</a></h2>
To show the status of all registered IPP printers on your network, run:
<pre class="man">
    ippfind --ls

</pre>
Similarly, to send a PostScript test page to every PostScript printer, run:
<pre class="man">
    ippfind --txt-pdl application/postscript --exec ipptool
      -f onepage-letter.ps '{}' print-job.test \;
